fix: standardize GitHub owner slug to Ultimate-Multisite across all docs and code (#887)

Replace all occurrences of the incorrect 'Multisite-Ultimate' slug with the
canonical 'Ultimate-Multisite' across README.md, inc/class-wp-ultimo.php,
and .wiki/Enhance-Integration.md.

The wrong slug was causing broken badge URLs, dead installation links, and
incorrect GitHub API calls for update checks. The admin notice in
ultimate-multisite.php already used the correct slug; now all files match.

Resolves #881
